Those sea textures are gorgeous! They're quite stark, though, and they tend to overwhelm the other features on a map. I dropped one into my Northlands map (CC3) to see how it looked. I got a pretty nice result by reducing the opacity to about 60% and giving it a 10 pixel blur.

You've got that mosaic land tile, and now this sea tile that looks oil-painted. Got anything in a watercolour? Actually, I think I have both of the plug-in bundles you mentioned; I think I'll reinstall them and see what I can come up with. Schedule permitting, of course.
